I have the same setup, and my only issue is at the switch level with CTDB. The IP does failover, however until I issue a ping from the interface ctdb is connected to, the storage will not connect.
If i go to the host with the CTDB vip, and issue a ping from the interface ctdb is on, everything works as described.
